Turn r_ops into a flexible array member to enable large, consisting of
up to 16 ops, OSD requests. The use case is scattered writeback in
cephfs and, as far as the kernel client is concerned, 16 is just a made
up number.
r_ops had size 3 for copyup+hint+write, but copyup is really a special
case - it can only happen once. ceph_osd_request_cache is therefore
stuffed with num_ops=2 requests, anything bigger than that is allocated
with kmalloc(). req_mempool is backed by ceph_osd_request_cache, which
means either num_ops=1 or num_ops=2 for use_mempool=true - all existing
users (ceph_writepages_start(), ceph_osdc_writepages()) are fine with
that.

bond_get_stats() can be called from rtnetlink (with RTNL held)
or from /proc/net/dev seq handler (with RCU held)
The logic added in commit 5f0c5f73e5ef ("bonding: make global bonding
stats more reliable") kind of assumed only one cpu could run there.
If multiple threads are reading /proc/net/dev, stats can be really
messed up after a while.
A second problem is that some fields are 32bit, so we need to properly
handle the wrap around problem.
Given that RTNL is not always held, we need to use
bond_for_each_slave_rcu().

Commit 85743f1eb345 ("net/mlx4_core: Set UAR page size to 4KB regardless

this fix fail to load if the PF driver runs with this commit.
To resolve this add a module parameter which disables that functionality

MVNETA_BM has a dependency on MVNETA, so we can only select the former
if the latter is enabled. However, the code dependency is the reverse:
The mvneta module can call into the mvneta_bm module, so mvneta cannot
be a built-in if mvneta_bm is a module, or we get a link error:
drivers/net/built-in.o: In function `mvneta_remove':
drivers/net/ethernet/marvell/mvneta.c:4211: undefined reference to `mvneta_bm_pool_destroy'
drivers/net/built-in.o: In function `mvneta_bm_update_mtu':
drivers/net/ethernet/marvell/mvneta.c:1034: undefined reference to `mvneta_bm_bufs_free'
This avoids the problem by further clarifying the dependency so that
MVNETA_BM is a silent Kconfig option that gets turned on by the
new MVNETA_BM_ENABLE option. This way both the core HWBM module and
the MVNETA_BM code are always built-in when needed.

Add ldmvsw.c driver
Details:
The ldmvsw driver very closely follows the sunvnet.c code and makes
use of the sunvnet_common.c code for core functionality.
A significant difference between sunvnet and ldmvsw driver is
sunvnet creates a network interface for each vnet-port *parent*
node in the MD while the ldmvsw driver creates a network interface
for every vsw-port node in the Machine Description (MD).
Therefore the netdev_priv() for sunvnet is a vnet structure while
the netdev_priv() for ldmvsw is a vnet_port structure.
Vnet_port structures allocated by ldmvsw have the vsw bit set.
When finding the net_device associated with a port, the common code keys
off this bit to use either the net_device found in the vnet_port or the
net_device in the vnet structure (see the VNET_PORT_TO_NET_DEVICE() macro in
sunvnet_common.h). This scheme allows the common code to work with
both drivers with minimal changes.
Similar to Xen, network interfaces created by the ldmvsw driver will always
have a HW Addr (i.e. mac address) of FE:FF:FF:FF:FF:FF and each will be
assigned the devname "vif<cfg_handle>.<port_id>" - where <cfg_handle> and
<port_id> are a unique handle/port pair assigned to the associated
vsw-port node in the MD.

Modify sunvnet common code and data structures to be compatible
with both sunvnet and ldmvsw drivers.
Details:
Sunvnet operates on "vnet-port" nodes which appear in the Machine
Description (MD) in a guest domain. Ldmvsw operates on "vsw-port"
nodes which appear in the MD of a service domain.
A difference between the sunvnet driver and the ldmvsw driver is
the sunvnet driver creates a network interface (i.e. a struct net_device)
for every vnet-port *parent* "network" node. Several vnet-ports may appear
under this common parent network node - each corresponding to a common parent
network interface. Conversely, since bridge/vswitch software will need
to interface with every vsw-port in a system, the ldmvsw driver creates
a network interface (i.e. a struct net_device) for every vsw-port - not
every parent node as with sunvnet. This difference required some special
handling in the common code as explained below.
There are 2 key data structures used by the sunvnet and ldmvsw drivers
(which are now found in sunvnet_common.h):
1. struct vnet_port
This structure represents a vnet-port node in sunvnet and a vsw-port
in the ldmvsw driver.
2. struct vnet
This structure represents a parent "network" node in sunvnet and a parent
"virtual-network-switch" node in ldmvsw.
Since the sunvnet driver allocates a net_device for every parent "network"
node, a net_device member appears in the struct vnet. Since the ldmvsw
driver allocates a net_device for every port, a net_device member was
added to the vnet_port. The common code distinguishes which structure
net_device member to use by checking a 'vsw' bit that was added to the
vnet_port structure. See the VNET_PORT_TO_NET_DEVICE() marco in
sunvnet_common.h.
The netdev_priv() in sunvnet is allocated as a vnet. The netdev_priv()
in ldmvsw is a vnet_port. Therefore, any place in the common code
where a netdev_priv() call was made, a wrapper function was implemented
in each driver to first get the vnet and/or vnet_port (in a driver
specific way) and pass them as newly added parameters to the common
functions (see wrapper funcs: vnet_set_rx_mode() and vnet_poll_controller()).
Since these wrapper functions call __tx_port_find(), __tx_port_find() was
moved from the common code back into sunvnet.c. Note - ldmvsw.c does not
require this function.
These changes also required that port_is_up() be made
into a common function and thus it was given a _common suffix and
exported like the other common functions.
A wrapper function was also added for vnet_start_xmit_common() to pass a
driver-specific function arg to return the port associated with a given
struct sk_buff and struct net_device. This was required because
vnet_start_xmit_common() grabs a lock prior to getting the associated
port. Using a function pointer arg allowed the code to work unchanged
without risking changes to the non-trivial locking logic in
vnet_start_xmit_common().

Split sunvnet.c into sunvnet.c and sunvnet_common.c.
Details:
Since the sunvnet and ldmvsw drivers will both use common sunvnet code,
move the functions (and support functions) anticipated to be common code
from sunvnet.c to sunvnet_common.c. Similarly, sunvnet.h was renamed to
sunvnet_common.h. The sunvnet_common.c code will be compiled into the
kernel and act as a library of functions that are linked by either
(or both) drivers when loaded.
Function names for external functions in sunvnet_common.c (to be
called by both the sunvnet and ldmvsw drivers) were tagged with a "_common"
suffix to clearly designate them as common functions.
No functional changes as of yet... just moved code verbatim to the new
sunvnet_common.c/h files.
Makefile/Kconfig support added to build sunvnet_common.c file. The code
is included in the kernel if SUN_LDOMS is defined/selected.
NOTE - per the SubmittingPatches documentation, since the code was just
moved from one file another, the code was NOT checkpatch'd in this commit
to aid in review.

The uas driver can never queue more then MAX_CMNDS (- 1) tags and tags
are shared between luns, so there is no need to claim that we can_queue
some random large number.
Not claiming that we can_queue 65536 commands, fixes the uas driver
failing to initialize while allocating the tag map with a "Page allocation
failure (order 7)" error on systems which have been running for a while
and thus have fragmented memory.

With commit 69bec7259853 ("USB: core: let USB device know device node"),
the port1 argument of usb_alloc_dev() gets overwritten as follows:
... usb_alloc_dev(..., unsigned port1)
{
...
if (!parent->parent) {
port1 = usb_hcd_find_raw_port_number(..., port1);
}
...
}
Later on, this now overwritten port1 gets assigned to ->portnum:
dev->portnum = port1;
However, since xhci_find_raw_port_number() isn't idempotent, the
aforementioned commit causes a number of KASAN splats like the following:

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for kernel v4.6. There is quite a
lot of interesting stuff going on.
The patches to other subsystems and arch-wide are ACKed as far as
possible, though I consider things like per-arch <asm/gpio.h> as
essentially a part of the GPIO subsystem so it should not be needed.
Core changes:
- The gpio_chip is now a *real device*. Until now the gpio chips
were just piggybacking the parent device or (gasp) floating in
space outside of the device model.
We now finally make GPIO chips devices. The gpio_chip will create
a gpio_device which contains a struct device, and this gpio_device
struct is kept private. Anything that needs to be kept private
from the rest of the kernel will gradually be moved over to the
gpio_device.
- As a result of making the gpio_device a real device, we have added
resource management, so devm_gpiochip_add_data() will cut down on
overhead and reduce code lines. A huge slew of patches convert
almost all drivers in the subsystem to use this.
- Building on making the GPIO a real device, we add the first step of
a new userspace ABI: the GPIO character device. We take small
steps here, so we first add a pure *information* ABI and the tool
"lsgpio" that will list all GPIO devices on the system and all
lines on these devices.
We can now discover GPIOs properly from userspace. We still have
not come up with a way to actually *use* GPIOs from userspace.
- To encourage people to use the character device for the future, we
have it always-enabled when using GPIO. The old sysfs ABI is still
opt-in (and can be used in parallel), but is marked as deprecated.
We will keep it around for the foreseeable future, but it will not
be extended to cover ever more use cases.
Cleanup:
- Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
includes.
This dates back to when GPIO was an opt-in feature and no shared
library even existed: just a header file with proper prototypes was
provided and all semantics were up to the arch to implement. These
patches make the GPIO chip even more a proper device and cleans out
leftovers of the old in-kernel API here and there.
Still some cruft is left but it's very little now.
- There is still some clamping of return values for .get() going on,
but we now return sane values in the vast majority of drivers and
the errorpath is sanitized. Some patches for powerpc, blackfin and
unicore still drop in.
- We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
implementations to use gpiochip_add_data() and cut down on code
lines.
- MPC8xxx is converted to use the generic GPIO helpers.
- ATH79 is converted to use the generic GPIO helpers.
New drivers:
- WinSystems WS16C48
- Acces 104-DIO-48E
- F81866 (a F7188x variant)
- Qoric (a MPC8xxx variant)
- TS-4800
- SPI serializers (pisosr): simple 74xx shift registers connected to
SPI to obtain a dirt-cheap output-only GPIO expander.
- Texas Instruments TPIC2810
- Texas Instruments TPS65218
- Texas Instruments TPS65912
- X-Gene (ARM64) standby GPIO controller"
